How to Force a Browser Refresh: A Guide to Overcoming Caching Issues

Force Browser Refresh: Avoid Lagging Styles and Scripts

Your browser often caches CSS, JavaScript, and other assets to optimize performance. However, when you make changes to your website, the browser may not apply these changes immediately. This can lead to frustration as you wait for your modifications to appear.

To overcome this issue, there are several methods you can employ:

General Solution

• Press Ctrl F5 (or Ctrl Shift R on Windows, Cmd Shift R on Macs) to force a browser cache reload, ensuring fresh content is loaded.

PHP

• Disable caching by setting the expiration date to a past time using headers:

header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

Chrome

• Disable the cache in Chrome's developer tools:

  • Open developer tools (F12)
  • Click the gear icon
  • Select "Disable cache" in the settings dialog

Firefox

• Type about:config in the URL bar
• Find the entry network.http.use-cache
• Set it to false
